ADDUP (1.0)

The program ADDUP.PRG requires the file ADDUP.DAT and should 
also be accompanied by this file ADDUP.TXT.

Blocks fall in groups of three. The object is to make 3 
consecutive blocks add to 15 in either a horzontal, vertical, or 
diagonal row. When this occurs the blocks dissolve and any 
remaining blocks above fall downward. The second objective is to 
avoid 3 consecutive blocks that add to 14. When this occurs the 
blocks are marked with X and cannot be elimated from the game.

Start the game with the F1 key. Exit the game with Escape or 
Undo. 

You maneuver the block group by the right, left and down arrow 
keys, or you can use the J, K, L keys. The left arrow or J moves 
blocks left, the right arrow or L moves blocks right. The down 
arrow or K changes the order of blocks in the three group that is 
falling. The space bar can be used to drop the group immediately.

The fall rate of the blocks is slow to give you time to look for 
combinations that add to 15. Your time decreases as the columns 
get higher increasing the difficulty.

Points are scored according to the numbers on the block 
eliminated.

SCORE shows the score for the current game. X SQR shows the 
number of X blocks in the playfield. BLOCKS shows the number of 
blocks eliminated for the most recent fall. MOST shows the 
largest number of blocks eliminated on a fall. TOTAL shows the 
total number of block eliminated during the game.

A high score file is maintained so you must have your disk 
unwrite protected in order for the file to be updated.

An alternate game could be played where the goal is to get the 
largest number of X blocks on the playfield. The program has no 
provision for retaining a list of these scores.

The program was made using GFA basic 3.50 and may be distributed 
freely providing it is accompanied by this text file.
